POWER ATTACHMENT.

Application filed May 29, 1922. Serial No. 564,359.

To all "Lo/tom` it may 'concern Be it known that l, Gnoncn NELSON, acitizen of the United States, residing at Center City, in the county ofChis/ago and State of lllinnesota, have invented certain new and usefulImprovements in Power Attachments, of wl'iich the following is aspecitication.

This invention relates to ypower attachments for automobiles and themain object is to provide a simple, eliicient, practical and easilyattached and detached device for transmitting power from an automobileto other belt diiven machinery. Further objects will be disclosed. inthe course of the following specification and are clearly illustrated inthe accompanying drawing, wherein Fig. 1 is an elevation of a rear wheelof 2O a motor vehicle, showing my attachment as applied thereto.

Fig. 2 is substantially a vertical, diametrical section on the line 2-2in Fig. l.

Referring to the drawing by reference characters 3 designates thehub ofan automobile wheel having spokes 4t, a felly 5 and a tire 6, all ofcommon and well known construction.

The power attachment consists of a belt pulley 'Y having integrallyformed spokes 8 and hub cup 9, the latter of which is made of a size tosnugly center and slide on the hub 3. Secured upon the insidey of thepulley rini 7 are a number of hooks 10, which are adapted tosimultaneously hook over the spokes l and hold the pulley in toward thewheel. A securing plate 1l is slidable in the cup 9 and is actuated by athreaded bar l2, which may be turned by a pin 13 or some other suitablemeans. Thus, after first placing the cup 9 over the hub 3, to center thepulley concentrically with the wheel, and hooking` the hooks 10 overcorresponding spokes 4, by turning up the bolt or bar 12 the plate 11will be forced 1n against the hub until the pulley is rigidly secured inplace on the wheel. With the pulley then connected up by a belt (notshown) it will be understood, that with the wheel jacked up, theautomobile can be used to drive stationary machinery in a convenient andpractical manner.

It is further understood that suitable modifications may be made in thedesign and structural details of this device, provided, liowever thatsuch modifications come within the spirit and scope of the appendedclaims. Having now therefore fully shown and described my invention,what l claim to be new and desire to protect by Letters Patent is:

l. A power attachment for an auto-vehicle wheel consisting of a pulleyhaving an integrally formed hub cap adapted to slidably andconcentrically engage the hub of the wheel, hooks near the periphery ofthe pulley for engagement with the spokes of the wheel, and meansoperative against the hub of the wheel for forcing the pulley outwardlyagainst the resistance of said hooks.

2. A power attachment for a motorvehicle wheel consisting of a pulleyhaving an integrally formed hub cup adapted to slidably andconcentrically engage the hub of the wheel, a member within the cupadapted to engage against the hub, means for actuating the member, anddetachable means for rigidly connecting the pulley to the spokes of thewheel.

3. A device of the class described consisting of a pulley having meansaround the rim thereof for securing it to a vehicle wheel, a hub cupformed integrally and concentrically with the rim of the pulley forslidable engagement with the hub of the wheel, hand operated meanswithinthe cup for adjustably securing it with respect to the hub,substantially as set forth.

In testimony whereof affix my signature.
